I had to do a system restore on my pc because of a virus and now i am not able open files that were encrypted. I'm using windows xp professional. How do I decrypt my files?

Hi ONOQUISIN, Thank you for your post. I give your these suggestions: 1. Try to logon with the account that is used to encrypt your file, open the encrypted file 2. If your pc was joined domain before, try to use domain admin to open the encrypted file 3. If the encrypted file still couldn't open, please try to use third party tool to decrypt the file like this tool If there are more inquiries on this issue, please feel free to let us know.
